Standard Equipment

• Polymer roller kit for profile support
• Pair of knurling cutters (Ø 80 mm)
• Set-up drawings for profiles requiring special kits
• Installation, operation, and maintenance manual
• Service spanners

Accessories (Optional)

• Special polymer roller kits for profile support
• Pair of special knurling cutters

• Adjustable roller kit
• Lower knurling kit
• 90° knurling kit

Design and Functional Features

• Steel cutters are highly wear-resistant with various types available depending on the number of cutting edges to accommodate different profile shapes.
• Width adjustment is achieved through transversal movement of the mobile head; vertical adjustment is independent for each head via Brushless motors (AS 142 Z) or control devices with decimal positioners (AS 140 Z).
• Cutter heads can be tilted ±10° to adapt to profile requirements.
• Quick-change rollers made of non-abrasive polymer material support profiles, including those that are not perfectly straight, due to structural flexibility.
• Idle conveyor rollers facilitate easier loading and unloading of profiles.
• Safety devices prevent mechanical overload on cutter assemblies.

Operational Recommendations and Limitations

• Operating pressure must be maintained at 7 Bar for optimal performance.
• Bar feeding speed should be adjusted within specified ranges to ensure quality knurling and avoid mechanical stress.
• Modifications and improvements can be made by the company without prior notice, indicating flexibility in machine customization.
